COMBINED GAS-SAVER AND PRIMER FOR AUTOMOBILES.

Application filed May s, 1918.

To all whom it may concern: Be it known that we, ORA E. Bnnnonons andEmma D. BURROUGHS, citizens of the United States, residing at Argos, inthe 5 county of Marshall and State of Indiana, have invented certain newand useful Improvements in Combined Gas- Savers and Primers forAutomobiles, of which the following is a specification.

saver and primer for automobiles.

The object of the invention is to provide adevice operable by a singlelever from the dash of a car to supply a priming mixture air from theexhaust manifold to the intake manifold of the engine, where by themotor may be easily started and a saving in gas effected.

Another ob ect is to provide improved means for automaticallycontrolling the priming charge operable the engine.

With the foregoing and other objects in View, which will appear as thedescription by the vacuum of proceeds, the invention residesin the.combination and arrangement of parts and in the details of constructionhereinafter described and claimed, it being understood that changes inthe precise embodiment of the in vention herein disclosed may be madewithin the scope of what is claimed without departing from the sp1r1t ofthe invention.

In the accompanying drawings Figure 1 represents a side elevation of the3 device constituting this invention with parts broken out,

Fig. 2 is a longitudinal section through the valve, and 1 Fig. 3 is avertical section through the primlng charge controlling device.

The preferred form of the invention illustrated herein comprises a valvecasing 1- havin a tapered valve plug 2 therein which exten s through thecasing and has a coiled bearing against one end of the casing and a pin4 extended through the projecting end of the valve so as to hold thevalve normally in connection with its casing as is shown clearly inFigs'l and 2.

Leading from the valve casing l is a pipe 5 connected at its other endwith a shell-like member 6 which is designed to fit over the exhaustmanifold of ail-internal combustion engine and to be clamped or securedthereto This casing 6 colexhaust manifold Specification of LettersPatent.

This invention relates to a combined gas the valve casing 1 at the sidePatented Dec. 9, 19115). Serial no. 233,383.

'and passes it through casing l for a scribed.

Another pipe 7 opens through one side of the valve casing 1, being hereshown with longitudinal alinement in the opening in which pipe 5 ismounted. This pipe 7 is detachably mounted in the valve casing l andcarries at its upper end a priming charge controlling device 8 hereshown in the form of a cylindrical container 9- having a plug 10detachably connected on its lower end a11d carried by pipe 2", said plughaving a valve seat 11 therein. Another plug 12 closes the other end ofthe cylinder- 9 and has a valve seat 13. with a pipe 1a leadingtherefrom and adapted to be connected with a fuel supply opening, notshown.

A pair of ball valves 15 and 16 are mount ed in the losures 10 and 1aand open in opposite Cllft. ons, being connected by a stem 17. A coiledspring 18 is mounted in pipe 7 and operates to hold the valve 16normally in closed position and the valve 15 open so that the fuel,preferably gasolene of a high grade, may flow thereinto through pipe-14from the supply tank. When the valve 16 is opened by suction from theengine against the tension of spring 18, the valve 15 is purposepresently to be de closed thereby cutting off communication between thecylinder 9 and the tank and pen nntting the contents of sald contamer topass out through pipe 7 and through valve 2 to the intake manifold, notshown, when the valve 2 is properly turned to bring the pipe 7' intocommunication with the passage 19 formed therein and which is here shownL- shaped (see Fig. 2).

The valve 2 has another L-shaped passage 20 arranged at right angles tothe passage 19 and which is designed to be brought into.

communication with the pipe 5 on the turn ing of the valve 2 in theproper direction, the two passages 19 and 20 being so disposed that whenone of these pipes is opened the other is closed. These passages 19 and20 are designed to alternately communicate with an lL-shaped pipe 21which leads from diametrically opposite and intermediate the spacebetween the points where the pipes 5 and 7 enter. This pipe 21 isdesigned to be screwed into the intake manifold of an internalcombustion engine, threads 22 being here shown for such connection. pipe21 has an apertured extension 23 ar- The free end of-this pipe 5 to thevalve ranged beyond the threads '22 which is designed to eXtend into theintake manifold for the passage of the combined air and gas and operatesto spray or break up the fuel particles to facilitate theirvolatilizationt lhe larger end of valve 2 is connected with a lever 2%,being here shown pivoted thereto'to hold against turning in relation tothe lever. suitable point convenient for operation by the driver of acar and is designed to be turned for turning the valve 2 in the casing1,-to bring either the passage 19 or 20 into operative relation toconnect its cooperating pipe with thepipe 21, when desired.

From the above description it will be obvious that when the lever 24:turned to bring the passage 1.9 into the position shown in Fig. 2,communication will be afforded between pipe 7 leading from the primingdevice to the pipe 21 leading to the manifold. When this valve 2 is sopositioned, the turning over of the motor will produce a vacuum in theengine causing suction through the intake manifold, pipe 21., passage 19and pipe 7. This suction will operate to open valve 16 against thetension of its spring 18 and close valve 15. When this occurs. thecharge contained in the cylinder 9 will flow out through pipe 7, passage19, and pipe 21 into the manifold, being broken up and sprayed asitpasses through the perforated extensions 23 of the said pipe .21.After the engine has been started, the valve 2 is turned through thelever 24 to cut off the communication between passage 19 and pipe 7, andif desired, the valve 2 may be turned to position passage 20 so that itwill be brought into communication with pipe 5 and pipe 21. iVhcn theparts are so disposed the'hot air collected in the casing 6 will bedrawn through pipe into the 'inanifold and operate to combine with thefuel to rarefy it and operate as a gas saver in a well known manner.

From the above it will be seen that the priming and gas saving devicesconstituting this invention are both operated and con trolled by thesame lever from a point convenient to the driver and that the amount ofthe priming charge is automatically regulated after the priming valve isopened from the dash. Furthermore, the charge is drawn into the intakemanifold by the This lever 2% extends to any vacuum of the engine andnot forced into as is the manner in devices of this character ordinarilyemployed. h

It is of course to be understood that this device may be constructed tofit the different manifolds of various cars and that it is not limitedfor use in connection with any particular car.

The foregoing description and the drawings have reference to what may beconsidered the preferred or approved form of our invention. It is to beunderstood that we may make such changes in construction and arrangementand combination of parts, materials, dimensions, at (LL, as may proveexpedient and fall within the scope of the claimed invention.

Having thus fully described our invention, what We claim as new anddesire to secure by Letters Patent, is

lin a device of the class described, the combination of a valve casinghaving a bore tapering toward one end With two longitudinally spacedopenings in one side wall, and another in the opposed wall at a pointopposite the middle of the space between said first-mentioned openings,a tapered plug valve extending through said bore and provided with areduced. extension at its smaller end projecting beyond said on ling,,a-coiled spring on said extension to cold the valve in close contactwith the casing, a pipe leading from one of said first-mentionedopenings and equipped with a hot air collector, another pipe openinginto the other of said first-mentioned openings and provided with anautomatically controlled priming device, a pipe leading from saidintermediately disposed opposed
